Integer multiplication is equivalent to repetitive addition, which is adding an integer a predetermined number of times. For instance, adding 4 three times results in the number 12 (4 + 4 + 4).

All whole numbers and negative numbers are considered integers.

This means that if we combine negative numbers with whole numbers, a collection of integers results.

An integer, which can comprise both positive and negative integers, including zero, is a number without a decimal or fractional portion. Integers include things like -5, 0, 1, 5, 8, 97, and 3,043. Z is a representation of a collection of integers.

A straight line of numbers is shown visually as a number line.

This line is used to compare integers that are spaced equally apart on an infinite line that extends horizontally on both sides.

The collection of integers can be shown on a number line much like other sets of numbers.

Hence, Integer multiplication is equivalent to repetitive addition, which is adding an integer a predetermined number of times. For instance, adding 4 three times results in the number 12 (4 + 4 + 4).

Since the value of x cannot be negative x value that makes line RQ tangent to the circle P at point Q is 6.

From the circle P, if Q is the tangent, It implies that at the tangent line, it is perpendicular to the radius.

Using Pythagorean theorem;

PQ² + RQ² = PR²

Where PQ = 9

RQ = 12

PR = (x + 9)

Applying (x + 9) to the formula

(9)² + (12)² = (x + 9)²

Using algebraic expression; (a + b)² = a² + 2ab + b²

x² + 18x + 81 = 36 + 144

x² + 18x + 81 = 225

x² + 18x + 81 - 225 = 0

x² + 18x - 144= 0

By employing the quadratic formula,

[tex]x =\frac{ -b+/-\sqrt{b^{2} - 4ac} }{2a}[/tex] where a = 1, b = 18 and c = -144

[tex]x =\frac{ -18+/-\sqrt{18^{2} - 4(1)(-144)} }{2(1)}[/tex]

[tex]x =\frac{ -18+/-\sqrt{324 + 576} }{2}[/tex]

[tex]x =\frac{ -18+/-\sqrt{900} }{2}[/tex]

[tex]x =\frac{ -18+/- 30}{2}[/tex]

[tex]x =\frac{ -18 + 30}{2}[/tex]

[tex]x =\frac{ 12}{2}[/tex]

x = 6

[tex]x =\frac{ -18 - 30}{2}[/tex]

[tex]x =\frac{-48}{2}[/tex]

x = -24

Knowing that the value of x cannot be negative then, the quadratic equation that yielded 12/2 = 6 makes the value of x = 6.

On solving the quadratic function x²+6x+8, the solutions x = -4 and x = -2 are obtained.

What is a quadratic function?

A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function. It is also known as the polynomial of degree 2 since the greatest degree term in a quadratic function is of second degree.

The given quadratic function is - x²+6x+8

To solve the function first multiply - 8 ×  x² = 8x²

Take the LCM of  8x².

8x² = 2 × 2x × 2x

Now, we need to form such two numbers that if added or subtracted gives 6x and when multiplied gives 8x².

8x² = 4x × 2x

6x = 4x + 2x

Factorize the equation using the numbers obtained -

= x²+6x+8

= x²+ 4x + 2x + 8

= x(x + 4) +2(x + 4)

= (x + 4)(x + 2)

This gives the value as x = -4 and x = -2.

Therefore, the solution points are x = -4 and x = -2.

The function g in vertex form is g (x) = –5x^2 – 3.

In this case, the parent function is:

f (x) = x^2

First, after the reflection across the x-axis, we will get:

f (x) = –f (x)

And, the function will be:

g (x) = –x^2

Then, vertically stretched by a factor of 5, we will get:

g (x) = –5x^2

Last, translated 3 units down, we will get:

g (x) = –5x^2 – 3

Thus, the vertex form of the function g will be:

His hourly pay rate is $18.38 if he works 34 hours a week an earns $32,500 per annum.

Per annum denotes yearly or annually. It is a phrasing used frequently to describe interest rates. In sentences like "I have a 4% mortgage loan" or "This bond pays interest at a rate of 6%," "per annum" is frequently left out.

An illustration is when a supplier offers a credit customer a 2% early-payment discount for paying an invoice in 10 days as opposed to the full amount in 30. In this instance, the supplier forfeits 2% of the invoice amount in exchange for receiving payment 20 days early.

We recalculate the amounts and multiply both the "2%" and the "20 days" by 18 to get the rate per year. The annual rate that results is roughly 36%.

Isa works 34 hours a week

There are total 52 weeks a years

In a year the time he works is = 52 × 34 h

                                                  =  1768 hours

His annual salary is $32,500

Then his hourly rate of income = 32500/1768

                                                    = 32500/1768

                                                    = $18.38

The exponential form of 72 can be written as [tex]2^{3}[/tex] . [tex]3^{2}[/tex] . It can be written using the prime factorization of the number.

The exponential form is an easier way of writing repeated multiplication involving base and exponents. To write the exponential form we have to write the prime factorization of that number. Prime factorization of the number is that number written as a product of prime numbers or as a product of powers of prime numbers. A basic exponential function from its definition is of the form f(x) = b x, where 'b' is a constant and 'x' is a variable. generally it refers to the positive valued function of a real variable. We can find the prime factorization of a number using factor trees, which are tools used to repeatedly break a number into products until all of the factors are prime numbers.

The standard form of the equation Y=(x-2)² + 4 is written as y=x²-4x+6.

A standard form serves as a gauge for how widely scattered the data is in comparison to the mean.

The data are grouped around the mean when the standard deviation is low.

A parabola with the point at its vertex represents this equation (2,4). On a coordinate plane, the equation can be graphed, revealing a parabola that extends upwards and has a minimum value of 4 at the point (2,4).

The factored version of the equation

Y=(x-2)² + 4 is y =  (x-2) (x-2) + 4

This representation of the equation demonstrates that it is the result of two binomials. When the common element is eliminated, the equation can be made simpler (x-2).

The equation is now more easily expressed as

y = (x-2) (x-2) + 4 = (x-2)² + 4.

Expanded form of the equation

Y=(x-2)² + 4 is expressed as y = x² - 4x + 6.

This representation of the equation demonstrates that it is the outcome of expanding (x-2)².

You may use this equation to determine the vertex of the parabola, which is (2,4). The vertex is the location where the parabola's value is at its lowest.

To find the formula of an exponential function from a table, you need to identify two points that fall on the exponential curve, and then use them to find the function's base.

The first step is to identify two points that fall on the exponential curve. Look for two pairs of x and y values that are not too far apart. For example, (1, 2) and (2, 4) are good choices.

Next, you use these two points to find the base of the function, which is the number b in the equation y = b^x. To do this, you take the ratio of the y-values and the logarithm of that ratio with base b. The logarithm of the ratio is equal to the difference of the x-values.

For example, if you have (1, 2) and (2, 4) you can find the base by taking log2(4/2)=log2(2)=1, which means that the base of the function is 2.

Now you have the base you can write the formula of the exponential function as y = 2^x.

It is important to note that you can use the same process with other bases, such as base 10 or base e, depending on the problem and the logarithm function you have available.

Answer: -36

Step-by-step explanation:

The end behavior of a polynomial function can be determined by looking at the degrees of the terms in the polynomial.

Generally, the highest degree term will indicate the end behavior of the function. For example, if the highest degree term is x^2, then the end behavior of the function will be that it will approach positive infinity as x approaches positive infinity and it will approach negative infinity as x approaches negative infinity. This can be illustrated by the following calculation:

f(x) = x^2 + 4x + 8

As x approaches positive infinity, the x^2 term will become much larger than the other terms, causing the polynomial function to approach positive infinity.

f(x) → +∞ as x → +∞

Similarly, as x approaches negative infinity, the x^2 term will again become much larger than the other terms, causing the function to approach negative infinity.
